All of these dolls appear to be the early versions of Karl Standfuss's German Minerva dolls in various sizes. Three have Germany on their shoulders, two the the faint Juno mark, one #2 and one who's cloth body is sewn on as such, the mark cannot be seen. Each is molded and painted metal with painted features, blond hair and cloth bodies. The three that have front access are marked Minerva. All measure from 11" to 16" tall

All have minor issues to the faces, some with chipping on the hair, face or both, but still display well.
Two appear to have their original bodies, maybe three
One appears to have a vintage replacement body
